,Extralink Chiron - gigabit PoE switch with SFP ports Extralink Chiron Pro is a 24-port Layer 3 switch with next-generation PoE power. It is targeted at IP MAN (metropolitan area network), government and corporate networks, Internet cafes. It is developed based on high-performance hardware and supports features such as efficient ACLs, flexible QinQ, 1:1 or N:1 VLAN switching, Ethernet OAM, carrier-level QoS and industry-level 10GE Ether-ring. It also supports Layer 3 routing protocol. High reliability Based on an advanced distribution mechanism and an efficient cross-physical link aggregation function, the logic control plane, service control plane and service data plane are separated. This allows Extralink Chiron Pro to support continuous routing redirection at Layer 3, avoiding service interruption due to a single failure. Telecommunications level Ethernet switch Chiron Pro supports telecom-level Ethernet protection protocol with less than 50 ms protection offset time, STP/RSTP/MSTP, active and backup uplinks, and LACP link aggregation to ensure high service reliability. Provides an excellent Ethernet OAM mechanism for real-time network health monitoring for rapid problem localization and detection. Supports In-Service Software Upgrade (ISSU) to ensure uninterrupted data transfer during system upgrades. Supports various L2 multicast functions, including IGMP-Snooping, fast-leave and trans-vlan.,Extralink Chiron Pro PoE Switch 24x RJ45 1000Mb/s PoE, 4x SFP+, L3, managed, 370W.
